Engine & Drivetrain


Developed and tested through an extensive R&D programme including top level Motocross events and the 2020 Dakar Rally with experienced campaigner Mick Extance.  The JT TwinStar range claims to be the lightest, most durable bi-metal sprocket on the market.

The JT TwinStar range has been developed to fit all key MX and Enduro models from Honda, Kawasaki, KTM, Suzuki and Yamaha. The sprocket will benefit riders of the popular green lane / enduro market.

JT TwinStar is manufactured from a lightweight aviation grade Ergal 7075-T6 Aluminium, precision made using state of the art laser cutting and CNC machining. The steel outer ring is heat-induction hardened to create a sprocket which will last up to six times longer than a standard 7075-T6 aluminium sprocket.

The JT TwinStar sprocket was run on the KTM 450 race bike of Mick Extance in the 42nd Dakar Rally, held for the first time in Saudi Arabia. Like all components on the machine, the sprocket was subjected to massive mileage, extreme heat plus most importantly grinding sand and mud.

The TwinStar is introduced to the UK market at an RRP of £29.95 +VAT for all 520 teeth sizes (up to and including 52 teeth). This special introductory price will be valid until the end of 2020.

All JT products are available at highly competitive prices through the comprehensive JT dealer network. Find out more at
